Abstract

Two enzymes of the Leloir pathway, UDP-GlcNAc pyrophosphorylase and UDP-Glc dehydrogenase, which are involved in the synthesis of activated sugar nucleotides have been cloned, overexpressed in Escherichia coli, and purified to homogeneity in only one step by chelation-affinity chromatography. The gene KfaC of E. coli K5 was thus demonstrated to encode UDP-Glc DH. Some properties of the cloned enzymes, such as stability, pH dependence, and substrate kinetics, were studied in order to facilitate the use of these enzymes in carbohydrate synthesis, especially in the synthesis of hyaluronic acid.

The two enzymes were overexpressed and used in the synthesis of Hyaluronic Acid.

      In the past years, the salvage pathways, in particular, have become the more frequently used enzyme module systems for the in vitro production of nucleotide sugars, as their simplicity makes them easier to optimize for large-scale production of nucleotide sugars, as outlined in the following chapters. The de novo synthesis of UDP-Glc is typically catalyzed by an enzyme cascade, including hexokinase (EC 2.7.1.1) or glucokinase (EC 2.7.1.2), phosphoglucomutase (EC 5.4.2.2), and UDP-glucose pyrophosphorylase (EC 2.7.7.9) [30,49–53]. However, the synthesis of UDP-Glc made a significant step toward productivity using sucrose synthase known from plants and bacteria [34,54] (Table S1).

      UDP-GlcA has also been shown to be a common precursor for nucleotide sugars including UDP-galacturonic acid, UDP-arabinose, UDP-xylose and UDP-apiose, which are essential for the biosynthesis of hemicellulose and pectin [2]. In mammals, UDP-GlcDHase provides precursors for an array of extracellular matrix glycosaminoglycans such as heparin and hyaluronic acid, and also catalyzes the crucial structural modification of xenobiotic toxins required for their eventual eliminations [3]. In microorganisms, the UDP-GlcDHase gene has been shown to be necessary for the biosynthesis of many virulence-associated exopolysaccharides [4–7], as well as of glycans such as xanthan gum [4,5] and gellan gum [8–10], which are of high industrial and/or medicinal values.
